Abstract
The utility model discloses a kind of free drainage structures on two dam of cushion pool, Er Daoba (2) including dam (4) and downstream, drainage hole (1) is equipped in the middle part of the dam body on two dam (2), cushion pool (3) are equipped between two dam (2) and dam (4), the downstream on two dam (2) is equipped with protection-apron (5).The utility model the extra water in cushion pool can be discharged by the drainage hole that two dam dam body of dam body is arranged usually.When dam flood-discharge, mesoporous aerial drainage can be first passed through, water in cushion pool is made to stop up height, after water cushion is formed, table hole is opened and carries out flood discharge.The utility model saves investment, improves the safety of engineering, safeguards convenient for Engineering Operation, particularly suitable to what is required in terms of the draining in need of two dam of cushion pool behind certain engineering dams.
Description
Technical field
The utility model relates to hydro-structure fields, more particularly, to a kind of free drainage structure on two dam of cushion pool.
Background technique
When traditional cushion pool needs to overhaul, the water in cushion pool to be drained using immersible pump, this mode water discharge time is long,
Power consumption is big, higher cost.And usually the normal phase with the presence of water cushion, is unfavorable for the stabilization of structure in cushion pool, therefore limits it
Application range.
When traditional cushion pool needs to overhaul, the water in cushion pool to be drained using immersible pump, this mode water discharge time is long,
Power consumption is big, higher cost.And usually the normal phase with the presence of water cushion, is unfavorable for the stabilization of structure in cushion pool, therefore limits it
Application range.
Utility model content
The utility model aim is to provide a kind of free drainage structure on two dam of cushion pool, it can usually pass through dam
Extra water in cushion pool is discharged the drainage hole of two dam dam body of body setting.When dam flood-discharge, mesoporous aerial drainage can be first passed through,
So that water in cushion pool is stopped up height, after water cushion is formed, opens table hole and carry out flood discharge.The utility model saves investment, improves work
The safety of journey is safeguarded convenient for Engineering Operation, requires in terms of the draining in need of two dam of cushion pool behind certain engineering dams
It is particularly suitable.
In order to solve this technical problem, a kind of free drainage structure on two dam of cushion pool of the utility model is in this way
:
A kind of free drainage structure on two dam of cushion pool, Er Daoba including dam and downstream, the dam on two dam
It is equipped with drainage hole in the middle part of body, cushion pool is equipped between two dam and dam, the downstream on two dam is equipped with protection-apron.
Further, the width of the drainage hole is 1~2m.
Further, the drainage hole floor elevation is higher than plunge pool floor elevation.
Further, the top bars in the armored concrete of the surface two Dao Ba are along river to arrangement.
Compared with prior art, although the utility model setting drainage hole have to the construction of two dam concretes it is slightly dry
It disturbs, but the ponding in cushion pool can be discharged in this notch after dam flood-discharge, improve the safety of cushion pool structure, and
Dam concrete is saved, economy is considerable, can be in hydraulic and hydroelectric engineering technical field wide popularization and application.The utility model section
Investment has been saved, the safety of engineering is improved, has safeguarded have to two dam of cushion pool behind certain engineering dams convenient for Engineering Operation
Need to drain the particularly suitable of aspect requirement.
Detailed description of the invention
Fig. 1 is the two dam discharge structure floor map of the utility model；
Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 is the B-B sectional view of Fig. 2；
Description of symbols: 1- drainage hole, bis- dam 2-, 3- cushion pool, 4- dam, 5- protection-apron.
Specific embodiment
The utility model is described in detail below with reference to drawings and examples.
It is as shown in Figure 1-Figure 3: the structure of the utility model, drainage hole 1 and dam body including being set to two dams, 2 dam body
Concrete, dam body drainage hole 1 are set in the middle part of dam body.Dam body inner concrete strength grade uses C20 or C25.Dam facing reinforcing bar
Concrete by reinforcing bar and coagulation local soil type at.Top bars in two dams, 2 surface armored concrete act in accordance with river to arrangement.
Cushion pool 3 is located at two upstreams Dao Ba, and dam 4 is set to 3 upstream of cushion pool, and protection-apron 5 is located at two dams, 2 downstream.Row
The width in water hole 1 is generally 1~2m, can also widen or contract according to project scale, in flood relief through dam, can make water in cushion pool 3
Stop up high, when not flood discharge, water extra in cushion pool 3 can be discharged.1 floor elevation of drainage hole is typically slightly above plunge pool floor height
Journey can also be raised or be reduced according to actual needs.
The utility model sequentially includes the following steps: (1) in the construction process and removes dam foundation coating, pours dam body coagulation
Soil, it is ensured that the dam foundation is seated on basement rock.(2) it is poured into 3 floor elevation of cushion pool or more to dam body, 1 two sides steel of drainage hole is installed
Template pours 1 two sides dam concrete of drainage hole.(3) two sides concrete is poured to crest elevation, is reached to strength grade of concrete
After mark, form removal forms drainage hole 1.
The utility model usually can by two dam of dam body, 2 dam body be arranged drainage hole will be extra in cushion pool 3
Water discharge.When dam flood-discharge, mesoporous aerial drainage can be first passed through, stop up water high, after water cushion is formed, open table hole into
Row flood discharge.
The specific application example of above only the utility model, there are also other embodiments, all uses for the utility model
The technical solution that equivalent substitution or equivalent transformation is formed, all falls within protection scope required by the utility model.
